Sweden
• Sweden is the third largest country in Western Europe with
nine million inhabitants
• Social care service delivery involve agencies of the 290
municipalities, and 20 regional county councils. Median size of
municipalities = 15.250 inhabitants
• National agencies and research councils, deals with research
and development, supervision of service quality and safety,
and the delivery of institutional care.
• The voluntary sector is considerable
• Social welfare states (e.g., low rate of unemployment, poverty,
drug use, violence)
• General trust among Swedes in collective solutions and in
government authorities

Sweden: What are the political issues that
need to be addressed?
Keywords: Ethics – Evidence – Transparency
not the technical issues concerning internal
/ external validity
Knowledge transfer / dissemination of
innovations need extensive support at a regional
level
Bring forward good examples
Stockholm evidence-based
Clearinghouse for social work
•
”Evidence-based medicine is the conscientious, explicit and judicious
use of current best evidence in making decisions about the care of
individual patients” (Sackett et al., 1996)
•
The general aim of “the Stockholm evidence-based Clearinghouse for social
work” is to build a bridge between professionals and research on “what
works”
•
It was launched
on 1st September, 2008

Stockholm evidence-based

Web-based service (at IMS’ homepage):
•
Provides information on interventions, assessment tools and
general knowledge (e.g., mechanisms)

The evaluation process
•
•
•
•
•
Selection of interventions to evaluate – starts with discussion in
IMS research council: Which interventions should we evaluate?
Which outcomes are important? What databases should be
searched?
All relevant studies with a RCT or QE (including data at baseline)
are reviewed
Use of a guide/protocol to assist the review process
Studies are evaluated for to their internal validity (i.e., can we trust
the result?)
Two independent reviewers evaluate each study. Any
disagreements are settled based on consensus with help from a
coordinator
22
Judging of internal validity
•
Selection bias
e.g., Are there any important differences between the groups?
•
Performance bias
e.g., Are researchers, participants and data collectors ”blind”?
•
Attrition bias
e.g., Any differences in size and type of attrition between the groups?
•
Detection bias
e.g., Are the outcome measures measured in the same way in all groups?
Potential bias is evaluated within and across each domain of bias
•
•
•
Low risk: plausible bias unlikely seriously alter the results
Unclear risk: plausible bias that raises some doubt about the results
High risk: plausible bias that seriously weakens confidence in the results
(from Higgins & Green, 2008)
23
Grading of evidence
• The scientific raiting scale is a modified version of a scale
developed at California Evidence-Based Clearinghouse for Child
Welfare (http://www.cachildwelfareclearinghouse.org/scientific-rating/scale)
• Based on statements in Flay et al., 2005 (Society for Prevention Research,
SPR)
• The scale is devided into five grades - A lower score indicates
effectiveness and a higher level of research support
• Grading of evidence is based on:
– Number of studies with a certain degree of internal validity (i.e., risk of
bias)
– If the practice is evaluated in usual care
– If the effect are sustained over time
– If the practice may cause harm
– If the practice is replicable
24
1. Effective practice with well-supported research evidence
•
•
•
•
•
At least two studies with low risk of bias, in different usual care or
practice settings, have found the practice to be superior to treatment
as usual (TAU).
If multiple effectiveness studies have been conducted, the overall
weight of the evidence supports the benefit of the practice.
In at least one study with low risk of bias, the practice has shown to
have a sustained effect at least one year beyond the end of
treatment.
There is no theoretical or empirical basis indicating that the practice
constitutes a substantial risk of harm to those receiving it.
The practice has a book, manual, and/or other available writings that
specify components of the service and describes how to administer
it.
2. Effective practice supported by research evidence
• At least one study with low risk of bias has found the practice to be
superior to treatment as usual (TAU).
• If multiple outcome studies (at least with medium risk of bias) have
been conducted, the overall weight of evidence supports the benefit
of the practice.
• In at least one study with low risk of bias, the practice has shown to
have a sustained effect of at least six months beyond the end of
treatment.
• There is no theoretical or empirical basis indicating that the practice
constitutes a substantial risk of harm to those receiving it.
• The practice has a book, manual, and/or other available writings that
specifies the components of the practice protocol and describes how
to administer it.
3. Practice with promising research evidence
• At least one study with medium risk of bias has established the
practice's benefit over no intervention (or placebo or waiting list) or is
found to be comparable to or better than treatment as usual (TAU).
• If multiple effectiveness studies with at least medium risk of bias have
been conducted, the overall weight of evidence supports the benefit of
the practice.
• There is no theoretical or empirical basis indicating that the practice
constitutes a substantial risk of harm to those receiving it.
• The practice has a book, manual, and/or other available writings that
specify the components of the practice protocol and describe how to
administer it.
4. Practice where the evidence fails to demonstrate effect
• At least two studies with low risk of bias have found that the practice
has not resulted in improved outcomes compared to no intervention
(e.g., placebo or waiting list), or that the practice is shown to be less
effective when compared to treatment as usual.
• If multiple effectiveness studies have been conducted, the overall
weight of evidence does not support the benefit of the practice.
• There is no theoretical or empirical basis indicating that the practice
constitutes a substantial risk of harm to those receiving it.
• The practice has a book, manual, and/or other available writings that
specify the components of the practice protocol and describe how to
administer it.
5. Concerning practice
• At least one study of low or medium risk of bias shows that the
intervention can cause serious harm, and/or there is a reasonable
theoretical basis suggesting that the practice constitutes a risk of
harm to those receiving it.
• The practice has a book, manual, and/or other available writings that
specify the components of the practice protocol and describe how to
administer it.
Beyond the five grades the scientific scale includes an additional category
(not rated - no number is given).
Practice with unknown effect
• There is lack of studies with a medium or low risk of bias.
• There is no theoretical or empirical basis indicating that the practice
constitutes a substantial risk of harm to those receiving it.
• The practice has a book, manual, and/or other available writings that
specifies the components of the practice protocol and describes how
to administer it.
Conclusions and summary Is there a sufficiently robust evidence base to identify good practice?
• What are the strength and weaknesses?
• Are there significant gaps that should be addressed?
• Is there an agreed approach to deciding what counts as evidence?
• Is there an agreed approach for judging the quality of the evidence
base?
• Is there a scope for working internationally to strengthen the
evidence-base?

Challenges
1. Lack of interest among the Swedish social work academia to
support an EBP, and train the future generations of social
workers accordingly
2. Lack of (inter)national agreement on how to grade evidence
3. Questions on the transportability of evidence-based
interventions between countries
4. Lack of reliable and valid measures of quality of services at a
local level (in order to motivate change)
5. Lack of an infrastructure for diffusion of innovations, and
knowledge transfer
